UPDATES
22 Jan 24 - Changed the frequency adjuster so you can now select your desired frequency step and adjust frequency based on that selection. For instance, use 10khz for CB FM, 1khz for HF SSB/LSB etc.
21 Jan 24 - Added a 'Round' button next to frequency readout which when clicked rounds the frequency to the nearest whole value.
11 Jan 24 - New realtime Audio visualizer added which also displays approx frequency of the audio peak. The only Websdr in the world to have this feature. Coded by me G0XBU.
9 Nov 23 - Callsign Lookup Tab improvements. User image now displayed (if available).
12 Oct 23 - User IP address replaced with approximate location lookup on the user tab. Replace this with your own callsign/username in the input box at the top of the page.
15 July 23 - AIR2 moved over to server 1 as it has a better antenna. Also added an HF KiwiSDR using a Wellbrook Loop. Thanks to Gerry M0VAA who has loaned it. Click the OWRX/Kiwi tab.
5 May 23 - XBU Weather API added to view my local weather station (basic info) within the weather tab.
3 May 23 - Callsign lookup tab now features a locator lookup and google map display.
23 Apr 23 - Callsign lookup feature added to a new tab.
6 Jan 23 - New Server installed as the old one kept crashing. This one is a Dell Optiplex 3070, Intel i5 running Linux Mint.
30 Dec 22 - Added a new style of S meter. Much more responsive and neater looking.
3 Nov 22 - Added an audio visualizer for playback of recorded files in the recording tab.
31 Oct 22 - Added the s graph plot to the audio tab to show signal graph.
23 Oct 22 - Added the ability to play recorded audio files within the websdr as well as download them. See the recording tab.
13 Oct 22 - Added the ability to change audio channels. Also added labels to the volume and Buffer range sliders
22 Sep 22 - Added a 'Beacons' tab which displays a realtime transmission schedule of the IARU Beacons.
3 Aug 22 - Added CW Filter change options. They automatically appear in the 'Filter Controls' tab when you select CW mode.
3 Aug 22 - Added DIG mode which sets USB at 3KHz and is enabled when you click on a data label such as FT8.
1 Aug 22 - Added a 'Loading Waterfalls' Splash page which waits for the page to load before displaying the Websdr and stops the page from looking half loaded!
6 Jul 22 - Lots of little adjustments to functionality: Added Display Off button, fixed the SuperZoom so the waterfall positions correctly, added a 'more contrast' button to help bring weak signals brighter, added a tab to go to my OpenWebRX server, Added a tab for quick access to the CB codes (i find this useful myself!), added links to the other server bands directly, plus other stuff behind the scenes for page layout!
23 Jun 22 - Major user interface update. New fresher look. The original is still available if you prefer, just go to the page layout tab to select
14 Jun 22 - Added a waterfall expander feature which enlarges the waterfall and fits it to the full screen.
8 Jun 22 - Added ON5HB/PA0SIM latest RSP1A drivers which now incorporate noise shaping giving a better dynamic range on the RSP devices (20m, CB and 80m) but it means edges of the band are lost.
7 Jun 22 - Finally fixed the random server crashes (thanks to Bas, ON5HB). Turns out the max bandwidth that can be safely used in the entire websdr is 8mb. We were using 10mb (total of all the bands added together). I've had to reduce some bands to make it in tolerance and more reliable.
6 Jun 22 - Added waterfall contrast/brightness control and a filter over the waterfalls to create colour (thanks to NA5B for this).
14 Feb 22 - Fixed the squelch when using AM mode (by reducing the bandwidth to 6khz instead of 8khz).
13 Feb 22 - Added the ability to make the main LCD display italic and also aligned it with the colour change when selecting different font colours in the "Colours" menu.
13 Feb 22 - Added a second airband as promised. This can be moved in freq depending on demand. Currently set to a center freq of 121.2MHz.
31 Jan 22 - Added a new theme based on a Yaesu FTdx101D. Try it via the 'Colours' tab. Its still a work in progress.
31 Jan 22 - Updated the mobile version of the site with correct bands etc
10 Jan 22 - Made some minor layout chages to better align buttons on the page and when changing web browser zoom levels to fit onto the screen better.
20 Dec 21 - Added a new drop down menu called 'Colours' which enables you to change font colours and background image to personalize the webpage. It will reset to default if you refresh the page.
19 Dec 21 - Raised CB and 4m antenna to 7.5m AGL. Doubt you'll notice that extra height though.
17 Sep 21 - Added buttons to enhance USB and LSB signals aswell as the original FM boost. These, when clicked, reduce the filter bandwidth and enable audio high boost. To revert, uncheck the buttons and reclick the USB or LSB mode button to default to original settings)
10 Sep 21 - Antenna position tab added. Click this to open a new window which displays current beam heading (relies on the PstRotator web server being open on my laptop so may come and go!)
21 Aug 21 - fixed the LCD band indicators so they correctly match the band you have selected
20 Aug 21 - Added an audio buffer control to increase audio delay to help with stuttering audio. Use the slider to adjust.
6 June 21 - Shortened the 80m band so it covers just 80 to try and reduce some QRM from strong out of band signals. Unfortunately means we lost 60m and some Aero stuff. Will see how it goes. Let me know what you think
28 April 21 - Added a new SDR Play RSP1a receiver to the CB Band. So using 3 in total now; 2m, 80m, CB
10 April 21 - Added new RSP drivers for the SDR play devices from Bas, ON5HB. Better AGC settings which enable hearing weaker stations while strong signals are present. Only caveat is the waterfall colours change alot while it adjusts itself.
March 21 - Lost the Upconverter on 80m (It didnt like 400w TX near it) so had to borrow the RSP1A from CB band and put a spare RTL on CB (RTL's dont go low enough for 80m).
Jan 21 - X Phase QRM eliminator added to the CB band
